Automated data collection using bar code

Using bar code technology to automate data collection provides a rapid and reliable alternative to paper-and-pencil tracking or keyboard entry into pocket or laptop computer. An array of bar code symbols is printed on a data menu, with a unique symbol corresponding to each possible observation. Bar code symbols are scanned using hand-held readers, which record the event, log the observation time, and store data for transfer to a personal computer. Advantages of the bar code monitoring system include: (1) ease of use by staff with minimal technical training, (2) reduced data entry errors and increased entry speed, (3) reliable portable operation, and (4) low-cost hardware. While the bar code system described here is used for behavioral monitoring in a residential treatment setting for the developmentally disabled, with minimal modification this system can be adapted for use in a wide variety of research and clinical applications.     

Just health care (II): Is equality too much?

In a previous essay I criticized Engelhardt's libertarian conception of justice, which grounds the view that society's obligation to assure access to adequate health care for all is a matter of beneficence [1]. Beneficence fails to capture the moral stringency associated with many claims for access to health care. In the present paper I argue that these claims are really matters of justice proper, where justice is conceived along moderate egalitarian lines, such as those suggested by Rawls and Daniels, rather than strong egalitarian lines. Further, given the empirical complexity associated with the distribution of contemporary health care, I argue that what we really need to address the relevant policy issues adequately is a theory of health care justice, as opposed to an all-purpose conception of justice. Daniels has made an important start toward that goal, though there are some large policy areas which I discuss that his account of health care justice does not really speak to. Finally, practical matters of health care justice really need to be addressed in a ‘non-ideal’ mode, a framework in which philosophers have done little.     

A program for constructing SVT tests: An alternative way of assessing text comprehension

The sentence verification technique (SVT), developed by Royer, Hastings, and Hook (1979), provides developmental and educational researchers with an alternative way of assessing text comprehension based on all of the information contained in a passage. Students must decide if test sentences have the same meaning as sentences that appeared in an original passage. The program described here automates the more laborious aspects of constructing SVT tests. The user must create a passage using a word processor. The program will prompt the user for information as needed. Finally, printable text files (SVT test and answer key) are generated. The program is written in BASIC for IBM and IBM-compatible computers.     

Abuse of persons with mental retardation: A literature review

The literature reports a number of reasons why abuse of people with mental retardation occurs. These causes of abusive behavior can be divided into three categories: organizational variables, staff characteristics, and client characteristics. The author examines each of the variables and presents recommendations for reducing their contributions to abusive behavior.     

Teaching dancercise to persons who are mentally handicapped: Programming transfer of stimulus control to a community setting

This study demonstrated procedures to promote the acquisition and transfer of stimulus control of an age-appropriate exercise skill. Three young adults diagnosed as mentally handicapped in a residential setting were taught a commercial dancercise routine during individual training sessions using a package of instructional procedures. A combination of a multiple baseline across subjects and a multiple baseline across response groups design showed that skill acquisition occurred only after each subject received training, and that performance did not generalize across exercise response groups. Training progressively incorporated more participants, new teachers, and new settings. Ultimately, subjects performed in a community dancercise class attended by 100 nonhandicapped persons.     

Probability learning and Piagetian probability conceptions in children 5 to 12 years old

This study focused on the relations between performance on a three-choice probability-learning task and conceptions of probability as outlined by Piaget concerning mixture, normal distribution, random selection, odds estimation, and permutations. The probability-learning task and four Piagetian tasks were administered randomly to 100 male and 100 female, middle SES, average IQ children in three age groups (5 to 6, 8 to 9, and 11 to 12 years old) from different schools. Half the children were from Middle Eastern backgrounds, and half were from European or American backgrounds. As predicted, developmental level of probability thinking was related to performance on the probability-learning task. The more advanced the child's probability thinking, the higher his or her level of maximization and hypothesis formulation and testing and the lower his or her level of systematically patterned responses. The results suggest that the probability-learning and Piagetian tasks assess similar cognitive skills and that performance on the probability-learning task reflects a variety of probability concepts.     

A controlled comparative investigation of psychological treatments for chronic sleep-onset insomnia

A sample of physician-referred chronic insomniacs was randomly allocated to either progressive relaxation, stimulus control, paradoxical intention, placebo or no treatment conditions. Treatment process and outcome were investigated in terms of mean and standard deviation (night to night variability) measures of sleep pattern and sleep quality. Only active treatments were associated with significant improvement, but the nature of treatment gains varied. In particular, stimulus control improved sleep pattern, whereas relaxation affected perception of sleep quality. All improvements were maintained at 17 month follow-up. Results are discussed with reference to previous research and guidelines are given for clinical practice.
